What gets filtered out of the blood in the nephrons due to high pressure? Select all that apply.
water
salts
fats
sugar
vitamins
protein
amino acids
ions
Answers
Answer:
Water, ions, glucose, fluids
Explanation:
This is because the nephron have network of cappilaries vessel called glomerulus . This glomerulus filter blood in the kidney to make urine. The hydrostatic force cause the filtrate to be filtered out through pressure.
The nephron also posses tubule which help to return needed or essential substances like protein, ions to the blood and then remove waste products from the blood.
In the troposphere, the higher the altitude (distance from the ground), the _______ the atmospheric pressure.
Answers
Answer:
Explanation:
The troposhere is the lowest layer in the atmosphere and the largest in mass taken about 80% of the mass.
The higher the altitude in the troposphere the lower the atmospheric pressure. At the bottom of troposphere the air is very warm and it gets cool as one moves through the troposphere. The density of the air also decrease with altitude or height above the sea level and this cause the cabins of high-flying jet aircraft to be pressurized.
The atmospheric pressure in the troposphere is lower with higher the altitude (distance from the ground).
What is troposphere?The troposphere is the lowest layer of the atmosphere of Earth. This layer contains the 75% of total mass of the atmosphere.
The variation in the temperature and atmospheric pressure in troposphere layer-
Temperature- The temperature of troposphere is decreases with increasing the altitude of this layer. Atmospheric Pressure- Troposphere ranges the atmospheric pressure between 1000 millibars to the 100 millibars. The value of atmospheric pressure is decreases with increasing the altitude of this layer. It drops 1 inch of Mercury per 1000 ft above the level of the sea.Thus, the atmospheric pressure in the troposphere is lower with higher the altitude (distance from the ground).

Charli thinks she does better on tests after she has had coffee in the morning. One morning she drinks a cup of Folger's coffee and then does very well (A-) on her chemistry test. She does it again before her next chemistry test and again does very well (B+). Now she is convinced her hypothesis is right?
Answers
Answer:
Her hypothesis is right.
Explanation:
The Charli's hypothesis is right because caffeine present in coffee helps in boosting of memory if consume it in a normal range. Recent research indicates that caffeine may enhance long-term memory of an individual. When the memory is boost so the individual has the ability to memorize more knowledge that leads to good performance in the examination so the caffeine present in the coffee helps Charli to give good results in the test and we can say that her hypothesis is right.

The reproductive handicap for sexual reproduction refers to __________. View Available Hint(s) The reproductive handicap for sexual reproduction refers to __________. diluted genetic investment in offspring dependence on hormonal cycles the need to provide energy for the offspring the difficulty of finding mates the need for maturation prior to reproduction
Answers
Answer:
diluted genetic investment in offspring.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
Generally, asexual reproduction produces more reproductive offsprings than sexual reproduction, this is referred to as a reproductive handicap.
Hence, the reproductive handicap for sexual reproduction refers to diluted genetic investment in offspring.
This ultimately implies that, the sexually reproducing female would have a 50% genetic material passed to its female and male offspring.
However, sexually reproducing female has 100% transfer of her genetic materials through asexual reproduction.

Answers
Answer:
Positive growth.
Explanation:
The general pattern of population growth in the greater Atlanta area from 1990 to 2000 is positive means there is increase occur in the population. The population of greater Atlanta in 1990 is 2,184,000 while on the other hand, the population of Atlanta is 3,522,000 in the year 2000. So there is 1,338,000 people increase occur in 10 years of duration from the year 1990 to 2000. So we can conclude that the pattern of population is positive and upward.

In the human body, organ-systems interact with each other to maintain homeostasis. Using the diagram below, explain how this system interacts with another in the body to maintain homeostasis?
Answers
Answer:
D
Explanation:
Im pretty sure tell me if im right
Homeostasis is a regulating process of the body in response to external environments, digestive system provides glucose for cellular respiration.
How do organ systems interact to maintain homeostasis?Organ systems in our body are regulated with each other and these interactions maintain homeostasis.
The respiratory system interacts with the circulatory system for gaseous exchange and the excretory system depends on the circulatory system for blood filtration, and the nervous system regulates the system through the brain.
Homeostasis is necessary because the external environment can change anytime, and the digestive system maintains food conditions according to the body's needs.
Therefore digestive system maintains homeostasis by providing glucose for cellular respiration.

Explanation:
mRNA, tRNA and ribosome are the major players because they perform a very important functions. Messenger RNA (mRNA) is a molecule in cells that carries instructions in the form of codes from the DNA to the sites of protein synthesis which is a ribosomes. Transfer RNA (tRNA) is a type of RNA molecule that helps in decoding a messenger RNA (mRNA) into a protein. Ribosome is an organelle present in the cell that is responsible for the production of proteins according to the instruction given by DNA.
